Question

89. What is the principle used in the separation of the mixture?

Answer 1

The principle used in the separation of a mixture depends upon the property or nature of constituent substances present in the mixture.

Some methods of separation are discussed below:

• A magnet, for example, can be used to separate iron bits from sand because iron attracts the magnet.
• We employ winnowing when the substance is light in weight.
• Evaporation is used when the substance is liquid.
• We utilize the sieving method if the substance is solid.

Therefore, the principle used in the separation of mixture depends upon the texture of the mixture present.
